Gov. Jay Inslee, pictured at an April 2017 rally in Seattle, signed the anti-"conversion therapy" bill Wednesday.

“Banning conversion therapy sends a loud and unequivocal message to LGBTQ youth: there is nothing wrong with you,” Washington state Sen. Marko Liias (D), the openly gay lawmaker who sponsored the bill, said in a statement.

“As a community, we love and support every person and we celebrate the diversity that makes us stronger. I am proud that Washington is standing up for our queer youth and I look forward to the day that these monstrous practices are illegal in every state,” he said.
